Kernel-based learning method tackles analytic operators and parametric PDEs

Researchers have developed a kernel-based learning method for analytic operators, specifically focusing on parametric partial differential equations (PDEs). The approach uses vector-valued reproducing kernel Hilbert spaces to derive finite-sample guarantees, showing that analytic kernels can achieve exponential convergence rates. The theory is applied to the solution operator of a parametric elliptic PDE, providing bounds that distinguish sampling and discretization errors and guide the coupling of mesh and sample sizes for optimal results, which are then demonstrated numerically.
